Did you grind out all that flashing or cut it out. I've found you can take out large chunks of aluminum pretty quick by drilling into it with a large sized drill bit. (start with small bit then get progressively bigger.) Or if you have a pneumatic body saw that could help too rather than grinding away at that stuff.

Re: [Picture Journal] Polishing the Intake Manifold

Haven't given up (yet) on this thing.

At one point I got discouraged so I started polishing just a corner so I wouldn't get discouraged.

That gave me a little more motivation so I kept working at it.

I then focused on the neck of the intake:

Before:

After:

Comparing it to the Millennia intake, I am beginning to be pleased with my progress:

Seems like the intake throat of the Millenia manifold doesn't have a knife edged divider like the imported Xedos curve neck manifold.

Easy to identify by the "casting ridge" that's on main plenum on the Xedos manifold that's not on the Millennia one.

Then wanted to smooth out the top cap:

I think I will keep thinning that plate out , see if I can get a little more clearance out of it.

Also shaved off the nub:

"Clanky" has since this work taken all my free time. It's going to be many weeks before I can start back on this.

Refills in bulk. Both the 2" and 1" refills I purchase sears brand in-store. There are 20-something misc assorted rough-fine drums very cheap. I didn't find them online so may be instore only. Any brand will do, others available online.

I break up the costs in two categories: Invested and disposed currency.

Then invested currency will be the cost of reusable tools: Power tools, mandrels, files.The disposed currency are the cost of materials that are not reusable: Sanding bands and sandpaper.Although you need to budget both categories before committing to hours upon grueling hours of monotonous, disparaging work, only the disposed currency is the actual cash value you're placing in your intake manifold... plus dozens of wasted labor hours you could have spent working overtime and making thousands of extra dollars.

There are many other tools and methods to polishing. I chose this particular route because I felt in control of how much material I was removing, and it offered a good deal of precision.But be warned... it is a long... long, boring, long, boring, long, long, boring, long, boring task.I also recommend a laptop connected to multiple series streaming sites. Just sit, sand and stare. It's a great way to get caught up on series that your friends are talking about, but you can't justify sitting down and dedicating time to watch that particular show. I can now talk to my friends about Trueblood (and how terrible it is) and have successfully not wasted any productive time watching it.
